DUMP-CAR.

Specification of Letters Patent.

Patented Feb. 12, 1918.

To all whom it may concern Be it known that I, FRANK S. INGOLDSBY, a citizen of the United States, residing in West Bloomfield township, in the county of Oakland and State of Michigan, have invented a certain new and useful Improvement in Dump-Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawmgs.

This invention relates to dump cars and has for its general object an arrangement of dumping doors providing for effectively and ouickly emptying a car, while at the same time securing the desired st"ength of frame work for the bottom of the car.

Experience has demonstrated that with dumping doors hinged to the central member of dump cars and extending the full length of the car from end to end thereof, that the rectangular frame work necessary for such door arrangement does not provide sufficient strength to resist distortion when the cars are subjected to unusual strains, such, for example, as glancing side blows or propelling the cars by engagement at one corner with a pusher pole extending transversely between trackways. Heretofore to obviate this difl'iculty the doors have been extended cnly a portion of the length of the car, the floor space between the ends of the car and the body bolsters being transversely braced and permanently closed. Thus manual labor is required for shoveling the load from such closed end portions of the car. This manual labor is not only expensive, but it delays the unloading, thereby keeping the car out of service, to the detriment of shippers as well as the transportation lines, and just now,

with a world war in progress, such delays are particularly serious. The main object of my invention is to reduce this Waste of time.

In carrying out my invention, I provide triangular doors at the end portions of the car particularly, one hinged to a central member of the car and the other to a diagonal member forming a stiffening brace, providing the desired strength for the car frame. An additional object of the invention is to so arrange these doors that they may be conveniently locked. v

I prefer to use a means for raising and lowering the doors similar to that, for example, described and claimed. in my prior Patent No. 1,013,552, issued January 2, 1912, but these triangular doors will be valuable no matter what means are used for raising and lowering them. The present invention is hereinafter more fully described in connection with the accompanying drawings, and the essential characteristics are sum- .marized in the claims.

Figure 1 is a side elevation of a car embodying my invention; Fig. 2 is a plan of ihe same' Fig. 3 is an enlarged plan of the end portion, showing the arrangement of the triangular doors; Fig. 4 is a vertical transverse section through the doors, showing them in their open position on a somewhat enlarged scale; Fig. 5 is a vertical transverse section showing the outer portion of the door and the locking mechanism. also on an enlarged scale; Fig. 6 is a plan of a car showing a triangular arrangement of doors throughout; Fig 7 is a plan showing a valuable arrangement of triangular door openings adjacent to the side doors of a box car, in which one, or closely adjacent, locking means may serve for two floors; Fig. 8 is an enlarged detail section similar to Fig. 5 showing a modified form of the door supporting beams.

In Figs. 1 and 2 I have shown a car of the general type of that illustrated in my prior Patent No. 1,000,175, issued August 8, 1911. Describing the invention as embodied in such car, 1 and 2 indicate opposite longitudinal sides and 3 the end walls of a car, the floor of which is shown as made up in a series of doors, 5 and 6, which may be hinged to the central sill member 7 extending throughout the length of the car. The use of rectangular doors of such a shape, arranged throughout the length of the car, weakens the same, so that a blow or pressure at the end, such as above described, may distort the car frame. Therefore, I arrange triangular doors 8 and 10 to close one of the rectangular openings between the body bolstcr 9 and the end sill. These doors permit the use of diagonal beams 12, greatly stiffening the car frame and preventing its distortion. These diagonal beams are shown as extending from the bolster 9 at its intersection with the central member 7 outwardly to the corners of the car frame, and it'is self evident that they act as struts or ties accord- Y ing to the strains which come upon them.

The doors- 8 and 10 close the triangular spaces thus formed. The door 8 is shown as carried on a floor beam 14 secured to the under side thereof and hinged at 15 to the central sill member 7, shown as an I-beam, which'may rest on a heavy sill structure, not shown. This beam 14 extends outwardly underneath the door to the side of the car adjacent the wide end of the door. The door 8 at-its narrow end, is supported on a short hinge member 16. The hinged floor beam 14 extends outwardly to the edge of the car where it is engaged by a supporting hook 17 hinged at 18 to the car side. A rearwardly extending hook 19 at the end of the floor beam provides a secure interlocking with this hook. The floor beam 14 is looped downwardly as indicated at 20 to pass beneath the diagonal beam 12 (Fig. 5).

The door 10 is supported on a floor beam 22 hinged at 23 to the beam 12 adjacent the broad end of the door. A short hinge member 24 secured to the door and hinged to the beam 12 is provided at the narrow end of this door. Another hook 17 is provided for engagement with the member 22 to securely lock it, another elbow or floor beam hook 19 causing the same interlocking at this point.

The doors are shown as made of sheet metal having downwardly and outwardly turned flanges 21 engaging the flanges of the surrounding frame members. Then when brought into closed position by wed e-shaped and wedge-acting portions of the 100kS 17, the floor of the car is tightly closed.

I prefer to arrange the center member, cross beams and diagonal beams so that they will shed material in both directions onto the doors, and accordingly I have shown curved metal strips on top of all these beams. These are preferablycurved about the center of the hinge member so that a plate-like strip 51, secured to the doors and having its edge beveled to fit the curved surface, may lie in contact therewith, insuring the material clearing itself from the car, all as more particularly shown in my prior Patents 1,000,175176-1 77, issued August 8, 1911.

Thus when both the doors are raised they are supported on hooks 17 which have upwardly extending arms pivoted to a bar 25 connecting all the hooks and connected by a link :26 to a lever 27 for actuating the hooks simultaneously to open all doors at that side of the car. On raising the doors anddrawing' the lever back to the position shown in Fig. 1, the hooks again engage the ends of the floor beams 14 and 22, securely holding the doors in place. These hooks are merely illustrative of any suitable mechfloor openings at the usual where doors 28 and 30 are hinged respectively to a central sill member 27 and diagonal struts throughout thelength of the car. It will be noted that a very strong car frame may be provided by using diagonal members 32, starting from the central transverse sill member or cross beam 31 and extending to the sides of the cars in opposite directions, and at the next cross beam 31 again extending from the central member to the sides, and so on to the end of the car, as shown.

For floor openings arranged at the doorways of box cars, these triangular doors may be used with the advantages above named, as well as the additional advantage of providing for conveniently locking the oorways. In Fig. 7, for example, the doors 38 and 40 are shown as hinged respectively to a central sill member 37 and cross beam 41, which, it will be noted, is a different arrangement of hinging from that above described.

If the floor beams 44 extend underneath the narrow ends of the doors 40 where they may engage the same, I may provide for this beam locking both of the doors 38 and 40 by raising the floor beam to engage the door 40, as shown in Fig. 8 at 45, anattached plate providing the hook 19. By this method the floor beam urges the door 4021s well as the door 38 upwardly to bring its flanges closely into engagement with the surrounding beams and struts, thus insuring tight joints lllGSl'X-K'l'lVQ- of loose hinges, as the wedge action of the hooks actually urges both doors upwardly when brou 'ht into locking position. Instead of locking both doors by one floor beam, I may provide for the doors 40, which are hinged to the cross beam 41, a longitudinal floor beam 46, turned outwardly at the end farthest from the hinge and extending into the side of the car, as indicated at 47, to engage another hook or locking means at the side of the car. Thus the hinged floor beams 46 and 44 may be locked at adjacent points, which has the advantage of permitting the use of a locking element controlled by the same means in case the arrangement of hooks and links described is not used.

I and which may be used in connection with any kind of mechanism. These triangular doors may be used only at the ends of the car, to provide proper stiffening, or they may be used throughout the car or at the middle portion only. It is immaterial to what'- particular floor beams the triangular doors are hinged. It will be apparent that such an arrangement not only'provides for the stiffening of the car frame but secures other advantages, for example, the locking of two doors at one point, and the most important advantage is that there is no dead space leftin the car from which the load must be removed by hand.

Having thus described my invention, what I claim is:

1. In a dump car, the combination of floor beams arranged to form triangular openings and triangular doors closing such openings.
